A fast pyrolysis study on lignin and macroalgae (non-conventional biomass) and wood and straw
(conventional biomass) were carried out in a pyrolysis centrifugal reactor. The product distributions and energy
recoveries were measured and compared among these biomasses. The fast pyrolysis of macroalgae showed a
promising result with on yield of 54 wt% dry ash free basis (daf) and 78% energy recovery in the bio-oil. The
physiochemical properties of the bio-oils were characterized with respect to higher heating value, molecular mass
distribution, viscosity, pH, density and elemental compositions. The lignin and macroalgae oil properties were quite
different to those of the conventional oils.
